In DSM-IV, to be diagnosed with Bulimia Nervosa (BN) or the provisional diagnosis of Binge Eating Disorder (BED), an individual must experience episodes of binge eating is "at least twice a week" on average, for 3 or 6 months, respectively. The purpose of this review was to examine the validity and utility of the frequency criterion for BN and BED.
Published studies evaluating the frequency criterion were reviewed.
Our review found little evidence to support the validity or utility of the DSM-IV frequency criterion of twice a week binge eating; however, the number of studies available for our review was limited.
A number of options are available for the frequency criterion in DSM-V, and the optimal diagnostic threshold for binge eating remains to be determined.
在 DSM-IV 中，要被诊断为神经性贪食症 (BN) 或暂定的暴食症 (BED)，个体必须经历暴食发作，分别为平均每周至少两次，持续 3 或 6 个月。本综述的目的是检验 BN 和 BED 的频率标准的有效性和实用性。
综述了评估频率标准的已发表研究。
我们的综述发现，几乎没有证据支持 DSM-IV 每周两次暴食的频率标准的有效性或实用性；然而，我们的综述可获得的研究数量有限。
DSM-V 中有多种频率标准的选择，暴食的最佳诊断阈值仍有待确定。
